N7 - MSV Strontium Mule

Finding this side quest is a two-pronged affair, not only because you'll need to find the exact location of the ship in question, but because you'll first need to be contracted to complete this side quest. The former is the simple part; it's the latter that makes things a little bit complicated. During the side quest known as N7: Archaeological Dig Site, you'll find a PDA near the end of the mission that will shed light on a Blue Suns black market ring, involving artifacts from that very dig site on Joab. Once you found that PDA and finish that side quest, you can complete this one at will. To find the MSV Strontium Mule, head to the Omega Nebula via Mass Relay. Once you arrive, you should be in the system known as Sahrabarik, but that's not where you need to be. You need to sub-light travel to one of its sister systems, an out-of-the-way location known as Arinlarkan. Once you arrive, the derelict MSV Strontium Mule should be easy enough to find, and subsequently board.

As soon as you enter the ship, get ready for a hell of a greeting. Blue Suns mercenaries will pour out of the far end of the room, and it'll be up to you to deal with them. At first, your best bet is to keep your distance from the enemy spawn point, doing as much damage as you can from afar. Eventually, this won't be a practical solution, because you'll find yourself wasting a lot of ammunition as you attempt to hit the more well-guarded, reserved enemies. This will force you to press forward to deal with any remaining enemies at closer quarters. There are some powerful mercenary officers mixed in with this otherwise unremarkable force of Blue Suns, so have your weapon at the ready, and be prepared for unwanted surprises. When all is quiet, you can press through the door at the back end of the room to proceed, though we implore you to first read the datapad on the ground en route. Seems the Blue Suns were ready for you, and their captain has a little "surprise" in store.

Once through the door, the coast will be clear for a short time. Take a moment to breathe, and search your surroundings. There's a computer terminal nearby, though examining it won't net you much information, so don't bother. Instead, begin climbing the grate catwalks leading ever-upward. When you reach the top of those ramps, you'll be assaulted by yet another crew of Blue Suns mercenaries. You should know how to deal with these guys by now -- eliminating some of their "fragile crate" cover will go a long way in killing them if you're having issues, since they won't have many places to effectively hide. When the coast is clear, you'll see three doors ahead, but all of them are locked. There's also a PDA on the ground. Read the contents of the PDA for a little bit of a story advancement, and then turn around and look in the other direction. There's a computer console up another brief series of ramps. Access the computer to turn off the electronic guard that's sealing the doors. All three of them should now be open.
